Abstract

Turbocompresseur à gaz d'échappement (1) pour un moteur à combustion interne, comportant un carter de turbine (2) dans lequel une roue de turbine (3) est logée rotative avec un arbre (4), l'arbre étant logé rotatif dans un carter de palier (5) au moyen d'au moins un segment de piston (6, 6'), de façon adjacente à la roue de turbine, et le carter de palier présentant un orifice d'amenée de lubrifiant (7) et un orifice de sortie de lubrifiant (8) sans pression pour la lubrification de l'arbre. Il est prévu, entre la roue de turbine et le carter de palier, un écran thermique (9) enserré par le carter de palier et le carter de turbine, présentant une ouverture reliée à l'orifice de sortie de lubrifiant (8) de manière à transporter du lubrifiant. La conception selon l'invention permet d'éviter que le trop-plein de lubrifiant dans le carter de palier ne s'écoule vers le carter de turbine.
